This is accomplished by testing various catalysts with a compound found in a feedstock to be tested, to determine the facility of the catalyst in hydrogenating, hydrosulfurizing, or hydrodenitrogenating the molecule, and hence the feedstock. In a preferred embodiment, the Double Bond Equivalence of the feedstock and molecule are determined, and catalysts are pre-selected based upon their known ability to work with materials of this DBE value. ## Claims ### Claim 1 A method for optimizing a layered hydro cracking catalytic process, comprising (i) contacting a molecule capable of (a) being hydrocracked as well as at least one of (ii) hydrogenation, hydrosulfurization and hydrodenitrogenation to a plurality of catalysts to determine an optimal catalyst for each of (i) and (ii), (b) layering the optimal catalyst for each of(i) and (ii) in a reaction chamber, and (c) contacting a feedstock to the layered catalysts under condition favoring formation of lower weight hydrocarbon from said hydrocarbon containing feedstock. ### Claim 2 (depends on 1) The method of claim 1, comprising layering the catalysts in a reaction zone based on their activity reacting with a model compound. ### Claim 3 (depends on 1) The method of claim 1, wherein said molecule is methylnaphthalene, dibenzothiophene, an alkylated or naphtalated derivative thereof, a basic nitrogen compound or a carbazole molecule, wherein said model compound boils in the range 180° C.-520° C. ### Claim 4 (depends on 2) The method of claim 2, further comprising determining double bond equivalence (DBE) of said feedstock, and contacting said test molecule to a plurality of catalysts suitable for hydrocracking a substance with a DBE of said feedstock, to determine an optimum hydrocracking catalyst for said feedstock. ### Claim 5 (depends on 4) The method of claim 4, further comprising contacting said test molecule to a second plurality of catalysts suitable for hydrogenerating, hydrodesulfurizing, or hydrodenitrogenating a substance with a DBE value less than said feedstock to determine an optimal, second catalyst. ### Claim 6 (depends on 4) The method of claim 4, wherein said hydrocarbons contained in said feedstock have a double bond equivalency of 24 or less. ### Claim 7 (depends on 4) The method of claim 4, wherein said feedstock has a double bond equivalency of 24 or less, and at least one of said catalysts for VGO hydrocracking catalyst. ### Claim 8 (depends on 4) The method of claim 4, wherein said feedstock has a double bond equivalency of 25 or more, and at least one of said catalysts is a catalyst designed for heavy feedstock. ### Claim 9 (depends on 1) The method of claim 1, comprising contacting said hydrocarbon containing feedstock to said reaction chamber at a temperature of from 350° C. to 450° C. ### Claim 10 (depends on 1) The method of claim 1, comprising contacting said hydrocarbon containing feedstock to said reaction chamber at a hydrogen feed rate less than 2500 liters per liter of feedstock. ### Claim 11 (depends on 1) The method of claim 1, comprising contacting said hydrocarbon containing feedstock to said reaction vessel at a pressure of from 100 bars to 200 bars. ### Claim 12 (depends on 1) The method of claim 1, wherein at least one of said catalysts contains a metal from Group VI, VII or VIIIB of the periodic table, or is a noble metal. ### Claim 13 (depends on 12) The method of claim 12, wherein said metal is Co, Ni, W, Mo, Pt, or Pd. ### Claim 14 (depends on 1) The method of claim 1, wherein at least one of said catalysts contains amorphous alumina, silica-alumina, titanium, Y zeolite, or at least one a transition metal inserted Y zeolite. ### Claim 15 (depends on 14) The method of claim 14, wherein said transition metal is Zr, Ti, Hf and combination thereof. ### Claim 16 (depends on 1) The method of claim 1, wherein said molecule is capable of being at least two of hydrogenated, hydrodesulfurized, and hydrodenitrogenated. ### Claim 17 (depends on 1) The method of claim 1, wherein said molecule is capable of being hydrogenated, hydrodesulfurized, and hydrodenitrogenated.
